Would you be worried?

Jaklyn • Hi, I`m Jackie

So I went for a dating scan this week and it’s said baby is measuring 6 weeks 1 day and the due date is 19 of November! I know I ovulate around the 15/17 of February! And only had sex that’s mark in the calendar down below! I google and the date that give me for ovulation is the 26th of feb and there is just no way because my partner and I haven’t had sex since the 17th

All my symptoms match the dates for the 9th feb but the baby is smaller then I had thought! I’m just worried that the baby isn’t growing right?

Has anyone else went through this and it be okay at the 12 week scan!
